Frequently opened signs often suffer from wind-closure, sometimes quite violently, with the danger of injury to operating personnel. Consequently, EMKA offer their 1097 program AISI 303 stainless steel telescopic door stay with push button release to ensure that once opened large doors/panels stay open as needed and keep personnel safe.
